How appraisals work
From VIN to value in four steps.
An appraisal is only as good as the information behind it. TrailerBook collects the right details first, then does the analysis.
- 1
Identify
Enter the VIN. We validate it, decode the model year, and match it to an existing TrailerBook profile.
- 2
Describe
Confirm the manufacturer, dimensions, GVWR, axles, factory options, and any added equipment.
- 3
Document
Upload guided photos — VIN plate, frame, tires, deck, hitch — so condition is assessed from evidence.
- 4
Appraise
AI reviews specifications, photos, and service history against current market data to produce your report.
Appraisals are an informed estimate, not a guarantee of sale price. Every report lists the details and evidence it was based on.
Service history
A maintenance record buyers can trust.
Well-maintained trailers are worth more — when you can prove it. TrailerBook keeps the proof attached to the VIN.
- Shop-verified records
- Work logged by a registered service shop is marked verified, so buyers know who did it.
- Owner-logged maintenance
- Owners can add their own work and receipts. It's clearly labelled as owner-reported.
- Transfers with the trailer
- When the trailer is sold, its history moves to the new owner. Personal details stay private.
- AI maintenance plans
- A schedule built for your trailer and how you use it, with one-tap Done and at most one reminder email a month.
